Just installed this on our 2013 GL1800. Had to be one of the easiest installs that I have done so far on our bike. Unlike the previous year models, no need to take the bike apart. Just lift a panel in the trunk, unscrew the radio stick the CB in place plug it in to the radio and put the radio back... Installed the OEM antenna with it. Did not route the cable behind the seat, wire was so short didn't feel like it was gonna reach, just tucked it in the back of the trunk under the carpet mat. Don't ever know it's there.
Did not set the SWR either and we had about a 2 mile range with another wing. Works perfect for talking to other bikes in our group.

just finished installing a cb on my GL1800,i have read the other comments about using an swr meter,and questioned that process. I called the Honda factory tecs,and was told that if the cb unit was a factory cb and a honda factory antenna that all is needed was for you to install it and play it.They called it plug am
nd play.The unit works great,iam very pleased with it,and yes it does balance the look of the bike

Had a lot of fun installing this and drilling holes in my one week old to me 2005 Goldwing. The first steps in the instructions deal with removing the trunk...unless you really just want to take the time removing the trunk I recommend leaving it right where it is. The 28mm hole can be drilled from the saddle side. I was able 2 use an 1 1/8 unibit (step bit) and get it done cleanly. Because my Goldwing never had a CB and only 3800 miles on it after 8 years the switches and controls for the CB were a little reluctant at first but worked great after a days ride and jabber on the ride. Also please make sure you have the SWR set/checked on you CB antenna so as not to burn up a $600 CB with an out of spec SWR.

This is one of those things that you really don't want to spend the money on because you might not use it very much, but that one time you need or want to use it you are VERY happy that you have it. I'm glad I got it, but sheesh, it's just too expensive. The most expensive Cobra system I could find at a Pilot station was only $400. Despite the cost, installation was a breeze, only 2 holes to drill (get a good set of step drill bits or a couple of hole saws, don't use paddle bits IMHO) and wiring was a snap. Range is limited, as to be expected, to about a mile or so, less in the mountains. Lost a star due to unnecessarily expensive for ancient technology.
